Improvement in pumps



UNITED STATES PATENT OFFICE.

JOHN GOLAND, OF BATAVIA, ILLINOIS.

IMPROVEMENT IN PUMPS.

To all whom t may concern:

Be it known that I, JOHN GoLAND, of Batavia, in the county of Kane and State of Illinois, have invented a new and Improved Pump; andl do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawing, making a part of this specification, said drawing being a vertical centra-l section of my invention.

This invention relates to an improved pump of that class in which a tubular piston-rod is employed, and which are designed to be used submerged or at the bottom of the well.

rlhe invention consists in the employment or use of a valve at the bottom of the pumpcylinder, in connection with a hollow piston provided with a valve and perforated, and all arranged to operate in such a manner that a continuous stream will be forced up through the tubular piston-rod as the piston is worked up and down.

To enable those skilled in the art to fully understand and construct my invention, I will proceed to describe it.

A represents the pump-cylinder, the uppe end of which is of semi-spherical form, and the lower end provided with a puppet-valve, B, opening` upward. The seat a of this valve may be in a cylindrical case, b, provided with side openings or water-passages, c, said box being attached to the cylinder A by screws d.

O represents the piston, which is hollow and of semi-spherical form, and having a puppetvalve, D, in its lower end, the seat e of which is screwed into the piston O. In the upper part of the piston O there are made holes or openings f, of any suitable number, the use of which will be presently shown.

E is the piston-rod, which is tubular and communicates with the piston C. This pistonrod may be operated through the medium of a lever, F, arranged as shown, or in any suitable way.

The pump-cylinder may be secured to any proper framing G, to retain it in proper position in a submerged state.

The operation is as follows: Vhen the piston O rises, the piston-valve D closes, and a suction is formed in the lower part of the cylinder A, the valve B in the lower end of the cylinder opening' upward, and the Water rising in the cylinder, following the piston. The water in the cylinder A above the piston O as the latter rises passes through the perforations f and up through the piston-rod E. As the piston C descends, the valve B closes and the piston-valve D opens, and the water will be forced up through the piston-rod E, and also through the perforations f in the piston O into the cylinder A, from which it is forced out through the piston-rod as the latter rises, as previously described. Thus it will be seen that a very simple and efficient double-actin g pump is obtained. l

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

The valve B in the bottom of the cylinder A, in combination with the hollow piston C, provided with the valve D, and perforated at its upper part, as shown at f, all arranged to operate as and for the purpose set forth.

JOHN GOLAND.
